Determination of lead in whole blood by filter furnace laser-excited atomic fluorescence spectrometry

Filter furnace laser-excited atomic fluorescence spectroscopy was used for the determination of lead in whole blood. The use of a Katskov filter has e nabled the direct comparison between lead fluorescence signals obtained wit h blood standards and water standards. Only a simple dilution of the blood was required. This direct correlation has allowed the interpolation of the lead signal of blood samples using a lead water standard calibration curve. NIST certified blood samples were analyzed using the method with excellent results.
